1. Singapore Air

SingaporeAir.com

Far and away the best experience possible in any first-class section anywhere in the world; Singapore Air doesn't just provide a private bedroom, it provides a private suite. It's not even really a suite, it's like a flying apartment. Every other offering on the list has a seat that turns into a rather comfortable bed. Singapore decided that was cheating and not quite kosher with the stress of international business. The airline will just give you a comfortable recliner and set it right next to a static bed designed by Jean-Jacques Coste, a renowned French yacht designer. You get a chair and a bed in the single cabins. If you happen to be traveling with someone, the option of a double bed is available. This is the absolute best experience you can have flying with any other passenger on board with you.
